Re: Changing the value of text box at run time in .net 2.0 windows application

show these portions of your code
1. how you create your serial port reader
2. where you get the text from the serial port and attempt to assign to the textbox's Text property.

Serial Port Declaration :
private SerialPort comport = new SerialPort();

reponse from com port : string response = comport.ReadExisting()

Changing the value : textbox1.text = response.Substring(0, 1)

There's nothing using threading in the code you've posted. I assume you're using a thread to read the port, is your serial port declaration in there?

BTW, there's a simple example on MSDN[^] - it might be worth comparing to your code.

I guess you're setting the text from within the comport_DataReceived event handler, which the SerialProt object calls from another thread. Either you read up on threading, or you don't use the event but put a timer onto your form (or control) and poll the com port from the timer's Tick event.

Hi all,

I have the following method: GetNodeByName, so the thing is that I can get hold of the specific treenode but how can I select it?? Confused | :confused:

public TreeNode GetNodeByName(TreeView treeView, string key)
{
    TreeNode[] nodes = treeView.Nodes.Find(key, true);
    return nodes.Length > 0 ? nodes[0] : null;
}

Can anyone please put some light on this issue
Many thanks in advance

TreeNode nodes = GetNodeByName(tView, tStripTxtFindLog.Text);
tView.SelectedNode = nodes;

Is this what you mean?

System.Net.Dns.GetHostByName( "www..." );

edit: apparently GetHostByName is obsolete - use GetHostEntry now Blush | :O

Thanks! I needed something as simple but I still cant see the ip address!!

I tried

public static string GetWebsiteIP(string websiteName)
{
    IPHostEntry host;
    string strIP = String.Empty;
    host = Dns.GetHostEntry(websiteName);
    foreach (IPAddress ip in host.AddressList)
        strIP += ip.ToString();

    return strIP;
}

But I still get the website name I pass Confused | :confused:

GetWebsiteIP("www.codeproject.com"); //the output is still "www.codeproject.com"

Thanks for your help guys!

Just tried it and it works for me Confused | :confused:

Also, a domain name can map to multiple IP addresses, so you might want to return a string[], or maybe just pick the first one?
